document.write( "We want to solve the problem by writing a proportion.\r\n" );

document.write( "    What quantity is the same to equate two sides of proportion ?\r\n" );
document.write( "\r\n" );
document.write( "        - The rate of work is the same per day and per worker.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "When 3 workers paint 2 rooms in 4 days, the rate of work is  \"2%2F%283%2A4%29\" = \"2%2F12\" = \"1%2F6\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "When x workers paint 12 rooms in 6 days, the rate of work is  \"12%2F%28x%2A6%29\" = \"2%2Fx\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "These two rates of work we want to equate (since they are equal)\r\n" );
document.write( "\r\n" );
document.write( "    \"1%2F6\" = \"2%2Fx\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From this proportion,  x = 2*6 = 12 workers.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  12 workers are needed.\r\n" );
